The California Science Center (sometimes spelled California ScienCenter) is a state agency and science museum located in Exposition Park, Los Angeles, next to the Natural History Museum of Los Angeles County and the University of Southern California. The museum includes many exhibits of aircraft and spacecraft, including Space Shuttle Endeavor, multiple hands-on galleries, special exhibitions, and IMAX movies.

Billed as the West Coast's largest hands-on science center, this museum is a public-private partnership between the State of California and the California Science Center Foundation. The California Natural Resources Agency oversees the California Science Center and the California African American Museum. Founded in 1951 as the "California Museum of Science and Industry", the Museum was remodeled and renamed in 1998 as the "California Science Center," which hosts the California State Science Fair annually.

The museum's history dates back to the first California State Exhibition building, which opened in Exposition Park in Los Angeles in 1912, the site of an agricultural fairground from 1872 to 1910. The brick and terra cotta building, designed by William D. Coates, Jr., state architect, and N. Ellery, state engineer,^[2] displayed agriculturally-based natural resources and industrial products from across the state, including ranching, fish and game, coal mining, gold mining, oil production, and lumbering, as well as some of the state's recreational attractions.^[3] After World War II, the building also featured exhibits about state science and technology industries.^[4][5]

In 1951, the exhibition became the "California Museum of Science and Industry". The State Exhibition building was renamed in honor of major donor and trustee Howard F. Ahmanson as the Howard F. Ahmanson Building.^[6] The hands-on interactive exhibits included themes on agriculture, transportation, electricity, energy, industries, and minerals.^[7]

In 1961, the museum opened a new science wing that featured "Mathematica: A World of Numbers... and Beyond", an exhibit sponsored by IBM and designed by Charles and Ray Eames to visually demonstrate fundamental mathematical concepts.^[8][9] Interaction stations demonstrated different concepts including celestial mechanics, the Möbius strip, multiplication, symmetry, and projective geometry. The original exhibit closed in 1998, and is now on display at the New York Hall of Science.^[10] The Hall of Health was added in 1968.^[7]

In preparation for the 1984 Summer Olympics, the museum added new exhibits on earthquakes and economics, and an IMAX theatre.^[11] The opening and closing ceremonies for the games were held in the Los Angeles Memorial Coliseum, which is adjacent to the museum.

The California African American Museum was founded in 1981 and housed in the California Museum of Science and Industry building until 1984, when its own facility was opened adjacent to the California Aerospace Museum.

In 1994, the museum's building was damaged by the Northridge earthquake.^[12] The California Museum of Science and Industry closed in 1996 to prepare for a new facility.

The "California Aerospace Museum" was also opened in 1984 adjacent to and operated by the California Museum of Science and Industry to coincide with the Summer Olympics.^[13][14] It was also known as Aerospace Hall but also commonly known as the California Air and Space Museum/Gallery and the SKETCH Foundation Gallery,^[15] and was the first major public work of architect Frank Gehry.^[16] The museum focused on the State's history as a leader in the aviation and aerospace industries and featured a giant, hangar-like space with aircraft and space vehicles and artifacts. The building, now known as the Air and Space Gallery, was closed in 2011.^[17] In 2012 the building was listed on the California Register of Historical Resources,^[18] but its future is unknown.

In 1988 the museum's leadership began a to develop a three-phase, 25-year master plan to transform the institution from a science museum to a science education facility.^[4] This new facility would be known as the California Science Center. The original museum building closed its doors in 1996 to prepare for the new construction, which was designed by Portland, Oregon-based Zimmer Gunsul Frasca Partnership.^[12] The original main building (Howard F. Ahmanson building) was redesigned, which the north facade of the Science Center retains the facade of former State Exposition Building that opened to the Exposition Park Rose Garden. However, the remainder of the original building was demolished.^[4][19] When Phase I was completed, the museum was officially renamed as the California Science Center, and was open to the public in 1998.^[12]

The grand opening of the new California Science Center, which includes:

• Science Plaza - Exhibits outside the main entrance of aircraft and science principles.
• Exhibits inside the new building
  • World of Life - Explores the science of life in five galleries.
  • Creative World - Highlights technology in transportation, communications and structures. Features include a virtual reality exhibit to play sports using virtual reality and an earthquake simulator.
  • Special Exhibits gallery - Exhibits in this room have included a Titanic exhibit, a magic exhibit, a toy exhibit, and the Human Body exhibit.
  • ExploraStore - Store specializing in scientific and educational items.
• A new seven-story IMAX theater

The new Ecosystems exhibit opened in 2010, allow guests to experience first-hand of the natural world.^[20] Other changes included:

• Renovated the historic Wallis Annenberg Building building into a new "Building for Science Learning and Innovation", opened in 2004^[21] The building includes the Amgen Center for Science Learning and the K-5 Science Center School, a public magnet school officially known as the Dr. Theodore T. Alexander Jr. Science Center School.^[22]
• SKETCH Foundation Gallery, Air and Space Exhibits - opened in 2002, a temporary gallery featuring interactive exhibits and artifacts on continuing loan from NASA and The Smithsonian Institution.^[4]
• Air and Space Gallery (former California Aerospace Museum) closed in 2011, with displays moved into the main Science Center in the SKETCH Foundation Gallery.

On April 12, 2011, the California Science Center received Space Shuttle Endeavour from NASA.^[23][24][25] It arrived at the Science Center on October 14, 2016, after it made its epic journey through the streets of Los Angeles.^[26] Before its arrival, a building was constructed to temporary house the Space Shuttle. It was on display in the "Samuel Oschin Pavilion" until December 31, 2023. This structure was designed by ZGF Architects and is planned to be replaced with the new Samuel Oschin Air and Space Center on the east side of the Science Center.^[27]

The Samuel Oschin Air and Space Center, which begins construction in 2022, a new 200,000-square-foot (19,000 m²) addition was formerly titled "Worlds Beyond".^[25][24] The new building is designed by ZGF Architects has an addition to the main science center. Construction work is scheduled to be completed in mid-2025 and will take several more years to install the artifacts and exhibits inside the building.^[28] An official grand opening is not yet announced. It will house a total of 150 new exhibits.^[29][30][31] Inside the new building will be include:

• Korean Air Aviation Gallery - This collection of approximately 20 authentic aircraft will be exhibited both on the floor and suspended in mid-air. It includes a replica of the Wright Brothers’ 1902 Glider; a Harrier T4 jump-jet; a historic F-100 Super Saber; and 50 feet of a real Korean Air Boeing 747 airliner, which will serve as the centerpiece of the Gallery.
• Kent Kresa Space Gallery - This collection examples of spacecraft from every stage of the U.S. human space program. This section includes the Apollo-Soyuz Command Module (ASTP), Mercury MR-2 and Gemini 11 space capsules, along with an array of engineering models of planetary probes, telescopes and Earth observation spacecraft.
• Samuel Oschin Shuttle Gallery - This will showcase the Space Shuttle Endeavour, in a 20-story-tall display, mounted in a vertical full-stack launch position, complete with an ET-94 external tank and a pair of solid rocket boosters. This section includes some parts from Endeavour, and an observation deck to allow guests to view the Space Shuttle at multiple levels.

General Admission for the California Science Center is free for their permanent exhibition galleries, various demonstrations, and other prominent aircraft and spacecraft. There are price charges for special exhibitions, educated films shown in their IMAX theater, and special activities that include a climbing wall, a motion simulator, and a high-wire bicycle.

This exhibit examines the processes of life and similarities among other microscopic organisms. A titan arum flower is now on loan from the Huntington Library, Art Museum and Botanical Gardens. It is also home to BodyWorks, a 15-minute show featuring Tess, a 50-foot animatronic human body simulator, with her animated friend, Walt, demonstrating how homeostasis works.

This two-story, 45,000-square-foot exhibit features display zones with live animals and aquariums about wildlife and adaptation in different ecosystems, including a river, desert, polar region, deep sea, ocean, island and urban areas, as well as the entire planet Earth,^[32] including a 188,000-gallon kelp tank populated with more than 1,500 live fish, kelp and other marine life with an acrylic tunnel which allows guests to feel surrounded by the sea life.

This exhibit inside an Casa Del Fuego apartment building showcase the importance of fire safety, and raise awareness on what to do if ever a fire did occurs. It was developed in partnership with the Children's Burn Foundation.

The Samuel Oschin Air and Space Center is an upcoming expansion of the California Science Center. This building will include three multi-level galleries, spanning four floors and covering over 100,000 square feet of exhibit space. It will also house special exhibits and events.

This exhibit examines the environment humans build to meet their needs for structures and transportation. It features an earthquake simulator shows the safety features used to construct the Science Center; and nearby hands-on exhibits demonstrate liquefaction and how reinforced vs. non-reinforced construction can determine the sturdiness of a structure.
